Application filed August 20, 1914.

To all whom it may concern:

Be it known that I, FREDERICK S. CULVER, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement inLoop-Banding Machines, of which the following is a specification.

This invention relates to pertain new and useful improvements in loopbanding machines, and pertains more especially to an improvement on, orattachment for, the machine forming the subject matter of the pat entgranted June 9, 1903, to F. S. Culver, NO. 730516.

The primary object of the invention is to provide meanswhichautomatically effects operation of the parts that are necessarilymanually operated in the patent above named, which parts will be fullydescribed and set forth in the following specification.

In the drawings, Figure l is a side'eleva tion of the machine disclosedin the aforementioned patent, showing the presentimprovement appliedthereto, and Fig. 2 is an enlarged section taken on the line 22 of Fig.1.

The same reference characters are employed in the course of thefollowing description as are used to designate corresponding parts inthe drawings of the patent in question.

The standard and the standard 6 support the driving shaft 6 the latterhaving a tight pulley b and loose pulley b. The belt shipper 0 ispivotally supported and has an arm 0 which depends below the bed A ofthe machine, which arm is held by the spring 0 against the stop 0 whenthe belt is on the loose pulley. The hand lever c is connected with therocking support of the belt shipper and is used to move the belt fromthe loose onto the tight pulley, and in doing this the arm a of the beltshipper, which engages with the bell crank lever 0 is moved to andengages with the second notch of the bell crank lever 0 which is held inengagement by the overweight c and holds the belt on the tight pulleyuntil the belt shipper is knocked off and the spring 0 draws the arm 0against thestop 0 thereby moving the belt from the tight to the loosepulley.

A disk 6 is loosely sleeved upon the driving shaft 6 and provided with agrooved hub d with which hub engages the Specification of LettersPatent.

forked or bifurcated end of the lever 03. As shown and described in mypatent, twister-hooks Z2 are carried by frames them selves each carriedupon a shaft journaled in the standard 6 said shaft being intergearedwith, and driven from the driving shaft 6 and which twister-hooks areactuated by and intergeared with said shaft. The disk I) is providedwith a pin Z2 ex tending through the standard 6 and pro jecting beyondthe latter so as to be engaged with and hold the frame against rotation,also as disclosed by my patent.

The lever d is pivotally supported and is provided with the arm 0Z thelower end of which engages with the notched bell crank lever (Z and isheld in such engagement by the counterweight 6Z sions arm (F. Theknockoff rods d and d are connected by the rod d with the block a.

The present invention consists of a vertical lever 1, pivotallyconnected intermediate its ends at 2 to a bracket 3,-which latterdepends from the bed A, the ends of the lever being forked orbifurcated. The lower forked end of the lever 1 straddles the knock-offrod cl", while the upper end of the lever has one end of a rod 4:pivotally secured in the fork thereof, the rod being guided in asuitable bearing X to allow slidingmovement of same. The lower end ofthe lever 1 is adapted to abut or engage the coupling X of the knock-offrods 03 and cl, while the rod t has its free end for abutting engagementwith the arm d In the patent in question, the disk 6 is necessarilythrown into operation by hand, following which the machine is started bythrowing the power into action, which is the cause of considerabletrouble due to carelessness on the part of the operator. In the presentinvention, the action is automatic in that when the rod d moves in thedirection of the arrow at, the coupling X will engage with the lower endof the lever 1, thereby sliding or moving the rod 4 so that the latterreplaces the arm (Z into the notch of the bell crank lever (Z thusmoving the disk 6 into proper operative osition for starting of themachine. The rst twisting having been performed, the end of the rod 03will contact with the bell crank lever (Z thus releasing the arm UP andmoving the disk Z2 so as to permit the final operation of the twisterhead.

Having thus described my invention, I

The spring d tenclaim as new and desire to secure by Letters Patent 1ling lever, and the knock-off rods, a horizontal sliding rod to engagethe controlling lever, a vertical lever pivotally connected intermediateits ends to the machine bed and connected at its upper end to thesliding rod,;the lower end of the vertical lever being bifurcated andstraddling one of the knock-off rods, and means on said knock-off rod toengage the lower end of the vertical lever;

2. In a machine of the type set forth, a rotatable twister frame,twister hooks rota table independently in said frame, means for holdingthe frame from rotating, means for throwingsaid holding means intooperative position, a knock-off rod, a sliding rod to operate thethrowing means, and connections whereby said shdlng rod is; operated bythe knock-off rod.

3. In a machine of the type set forth, in

combination with a; rotatable twister frame,

rotatable twister hooks rotatable independently in said frame, means forholding the frame from rotating, means for throwing said holding meansinto operative position, a knock-off rod, and means whereby uponactuation of the knock-off rod said throwing means will be automaticallymoved to throw the twister hooks into operative posi tion.

4. In combination with a rotatable twister frame, twister hooksrotatable independentlyin said frame, means for holding the frame fromrotating, means for throwing said holding means into operative position,sliding means to engage and actuate said throwing means, a knock-offrodfand a pivoted means connected to said sliding means and engaged withthe rod whereby upon movement of the rod the pivoted means will beactuated to thereby actuate the sliding means so as. to automaticallymove the throwing means into operative position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
